What I have come to realize is that the global financial crises since the installation of a rule based global system working with the UN and the Bretton woods institutions has been on decline and a new world order based on the sovereignty of countries is shaping up. The main reason for this is that the economies of countries tend to be worse when there's appeal to the rule based system. It's been called the Triffin paradox.
Hence the resurgence of neo-fascist- populist ideology in Trump and the US, Israel, China, Russia ... A new political order is in the making right now.
The re-alignments and moves made by these countries are a major source of turbulence, plus the ineffectiveness of contemporary economic theories. We are living in chaos in fact.
